Blacktoe is one of the few locations in The Guilt of War that isn't based off a pre-nuclear settlement. It is ran by a group of troublemakers, but they allow the Floridian Government to come and go and even station troops there. It comes without question that this area isn't visited much in the entirety of the series. Leo once did business with the original inhabitants, but the Troublemakers killed them all and took over the town.
The town is led by troublemakers, which makes the whole idea of even going there dangerous.
